ESD5482MUT5G Equivalent & Substitute Parts

Part Overview

The ESD5482MUT5G is a transient voltage suppressor (TVS) diode manufactured by onsemi, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 3.3V reverse standoff voltage, 7.8V maximum clamping voltage, and 1A peak pulse current rating in a compact 0201 package form factor (2-X3DFN 0.6x0.3mm). The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESD5482MUT5G is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Reverse Standoff: 3.3V (Max)
• Package / Case: 0201 (0603 Metric) with 2-X3DFN footprint
• Bidirectional Channels: 1
• Mounting Type: Surface Mount
• Zener diode type

Secondary Compatibility Factors:

• Voltage - Clamping (Max) @ Ipp: Must not exceed application requirements
• Current - Peak Pulse (8/20µs): Must meet or exceed circuit protection needs
• Operating Temperature Range: Must cover application environment
• Capacitance @ 1MHz: Lower values preferred for high-frequency applications

The three substitute parts listed below maintain the core 3.3V reverse standoff voltage and 0201 package specification, ensuring mechanical and electrical compatibility with the original design. Variations in clamping voltage, peak pulse current, and capacitance reflect different protection profiles suitable for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

ESD7481MUT5G (onsemi): This substitute maintains onsemi manufacturer continuity with active product status. It shares the identical 3.3V reverse standoff voltage and 0201 package footprint. The higher 12V clamping voltage and 3A peak pulse current provide enhanced protection capability for circuits requiring greater transient suppression. The significantly lower 0.25pF capacitance at 1MHz makes this option suitable for high-frequency RF antenna applications. Operating temperature range is reduced to -40°C ~ 125°C compared to the original -55°C ~ 150°C specification.

PESD3V3C1BSFYL (Nexperia USA Inc.): This substitute offers the closest electrical match to the original part, with identical 3.3V reverse standoff voltage and the lowest clamping voltage at 5.5V. The 9A peak pulse current rating provides significant protection margin. The 0.2pF capacitance is the lowest among all options, making it optimal for sensitive RF and high-frequency circuits. Product status is active with ROHS3 compliance. Operating temperature range is -40°C ~ 125°C. Package designation is DSN0603-2, which is mechanically compatible with the 0201 form factor.

PESD5V0V1BSF,315 (NXP USA Inc.): This substitute differs in reverse standoff voltage at 5V (Max) rather than 3.3V, making it suitable only for applications where the higher standoff voltage is acceptable. It maintains the 1A peak pulse current rating matching the original specification. The 12.8V clamping voltage and 4.6pF capacitance are intermediate values. Operating temperature range matches the original at -55°C ~ 150°C. Product status is active. This option is appropriate for general-purpose applications where the voltage differential does not impact circuit operation.

All three substitutes maintain active product status, ensuring long-term availability and supply chain stability compared to the obsolete ESD5482MUT5G.

Frequently Asked Questions (FAQ)

Q: Can I use PESD5V0V1BSF,315 as a direct replacement for ESD5482MUT5G?

A: PESD5V0V1BSF,315 has a 5V reverse standoff voltage compared to the original 3.3V specification. This higher standoff voltage means the diode will not begin conducting until a higher voltage threshold is reached. Use this substitute only if your circuit design accommodates the 5V standoff voltage without compromising protection requirements.

Q: Which substitute offers the best high-frequency performance?

A: PESD3V3C1BSFYL provides the lowest capacitance at 0.2pF @ 1MHz, followed by ESD7481MUT5G at 0.25pF. Both are suitable for RF and high-frequency applications. PESD3V3C1BSFYL is specifically designated for RF antenna applications and offers the tightest capacitance specification.

Q: Are all substitutes compatible with the 0201 package footprint?

A: Yes. All three substitutes use 0201 (0603 Metric) package specifications. ESD7481MUT5G and the original use identical 2-X3DFN (0.6x0.3) supplier packages. PESD3V3C1BSFYL and PESD5V0V1BSF,315 use DSN0603-2 supplier packages, which are mechanically compatible with the 0201 footprint and can be used in the same PCB layout.

Q: What is the difference in peak pulse current ratings?

A: The original ESD5482MUT5G and PESD5V0V1BSF,315 both handle 1A peak pulse current (8/20µs). ESD7481MUT5G handles 3A, and PESD3V3C1BSFYL handles 9A. Higher current ratings provide greater protection margin for circuits experiencing larger transient events. Select based on your circuit's expected transient current levels.

Q: Which substitute has the widest operating temperature range?

A: Both the original ESD5482MUT5G and PESD5V0V1BSF,315 operate across -55°C ~ 150°C. ESD7481MUT5G and PESD3V3C1BSFYL are limited to -40°C ~ 125°C. For applications requiring extended temperature operation, PESD5V0V1BSF,315 matches the original specification, though with the caveat of the higher 5V standoff voltage.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All substitutes except PESD5V0V1BSF,315 explicitly specify MSL 1. This classification ensures the components can be stored and handled without special moisture control procedures.

Q: Are all substitutes RoHS compliant?

A: ESD7481MUT5G and PESD3V3C1BSFYL explicitly state ROHS3 compliance. PESD5V0V1BSF,315 does not specify RoHS status in the provided data. Verify RoHS compliance requirements with your procurement or quality assurance department before final selection.
